Lascap's Triangle, a synopsis.
A play on the name Pascal - the Lascap's Triangle - is a popular and simple mathematical puzzle presented to high school students to solve. Following a few subtle clues it is possible to decipher the puzzle. As I told a student trying to solve this puzzle "anything that be encrypted can be decrypted if you work at it long enough." An expression for the elements E(n,r) of Lascap's Triangle is derived by inspection.
